Nikon just released firmware updates for nine different DSLR cameras. This was first on the Nikon Rumors website where they announced firmware updates for the D4, D4s, Df, D800, D800E, D810, D810A, D7100 and D7200 cameras. Most of the changes are for adding AF-P lens support to these cameras which Nikon had previously said were incompatible with the new AF-P 70-300mm lens.
At first it seemed to be great news, but in reading some of the comments posted by others in the comments section, it seems that this new Nikon firmware update is creating issues with third party lenses. A number of people that have Sigma 35mm f1.4 ART and 50mm f1.4 ART lenses have reported that after downloading the new firmware, their Sigma lenses did not autofocus properly anymore.
Just something to be aware of if anyone plans on updating their cameras with the new firmware so they can use the Nikon AF-P lenses and also has Sigma lenses.

Nikon produces their lenses to work with future firmware updates. Third party lenses are not so designed. Disadvantage, third party glass.
